public class SegmentationBackedRegion extends BinaryRegion
Defines a binary region that is backed by the label array of a region segmentation. A SegmentationBackedRegion instance does not have its own list or array of contained pixel coordinates but refers to the label array of the associated BinaryRegionSegmentation instance.
